Britney Spears' Camp Hit Back At The Wanted

Britney Spears' camp have responded to claims made byThe Wanted that they were Christina Aguilera, branding [uuid=163e673d-df50-43d7-a9e5-82a5ed9b4f4f]Xtina "a total b*tch" after she reportedly ignored them backstage at The Voice USA.

A spokesperson for Spears told E! Online: "What's even more interesting than the false allegations they made is the fact that they have claimed to be picked on by two female pop stars in just a few days."

The rep then joked: "Look out Lady GaGa - there are still three days left this week."

Following their claims about Aguilera, Tom has since issued an apology to the Genie In A Bottle star, telling TMZ: "We shouldn't have said it, to be honest with you. We just think manners cost nothing, you know what I mean?

"The rest of the judges were really nice and she didn't look at us or even talk to us but we apologise for the comment but we get a bit frustrated. It's just common courtesy."
